This is the one, the moment when the Next Generation not only equaled everything great about all the Trek that came before it, but surpassed it and defined what Star Trek really is and what makes it the greatest work of science fiction above all others. It’s almost breathtaking to watch this episode knowing that you’re watching greatness unfolding before you. You can even tell from the performances in this episode that every actor knew they were doing something special. From here on out thru the rest of this series and DS9, Star Trek was fully realized and running on all cylinders. The likes of a show like this (and DS9) may never be seen again.
